SOLE-SEWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 581,440, dated April27, 1897.

Application filed May 4, 1896. Serial No. 5 90,137. (No model.)

To all whom t may concern:

Be it known that I, FRANK E. STANLEY, of

Swampscott, county of Essex, State of Massachusetts, have invented anImprovement in Sole-Sewin g Machin es, of which the followingdescription, in connection with the accompanying drawing, is aspecication, like letters on the drawing representing like parts. Thisinvention has for its object to improve the construction of sole-sewingmachines of the class using a rotating work-supporting horn. These hornsare commonly provided with wax-pots, in which the wax has to be keptheated, and the horn has to carry the heating means, and greatdifficulty is experienced in making and keeping tight the steamconnections.

I have devised means whereby the wax-pot is located at the foot of thehorn and preferably on the stationary frame of the machine, by which thehorn is supported.

The drawing, in section, shows a rotatable horn and part of theframework of a sole-sewing machine.

The framework A is and may be of the shape commonly found in the McKaymachines, it having an arched or other shaped bracket A', which receivesa bearing c, provided at top with a collar a', on which rests a shouldera2 of the spindle E of the horn E of usual shape and size.

The horn has its tip provided with any usual whirl e', which cooperateswith the usual hooked needle (not shown) to make the stitch.. The tip isrotated by the shafts b c, the gears h c d d d2 cl3, the latter gearbeing connected to the upper end of a hollow shaft e, extended throughthe lower end of the horn-spindle and the bearing c, where it isprovided with a gear 4o f, which is engaged and rotated in any usualmanner commonly practiced in connection with a horn.

The wax-pot D is herein shown as located at or near the lower end of thehorn, it being represented as held in place between stands g.

The threadtin the shape of a cop or ball orin other usual mass is shownas led into the wax in the stationary wax-pot I) and out therefromthrough a suitable wiper g, and thence into the lower end of the hollowshaft e, and from said hollow shaft about the tension sheave or device71J and over other suitable guides h h2 to the usual whirl.

I have not shown anyheating means for the wax-pot D, but it may be ofany usual or suitable construction and be heated by steampipes orotherwise, the steam-pipes, if used, communicating with a suitablesource of steam-supply.

Making the shaft e at the center of rotation of the horn hollow enablesthe thread to be taken directly from the wax-pot through the said shaft,and it cannot be wound about the shaft as the latter rotates and thethread can be led from any point outside the horn.

The horn-spindle is surrounded by a waterjacket B, in turn surrounded bya cylindrical jacket C, which is heated by steam or hot water and byconduction heats the water in the jacket B, pipes in communication withthe latter jacket being carried up within the horn toward its tip tokeep the horn and thread warm.

The jackets B and C are and may be all as provided for in United StatesPatent No. 503,084, dated August 8, 1893, so need not be herein furtherdescribed.

The spindle E is removed at its upper end somewhat from the shaft e, soas to constitute thereby a heat-chamber to maintain the shaft properlyhot.

The sheave h has its periphery arranged within the line of the centralopening of the shaft e, so that the thread from the ball in the wax-potmay be led directly therefrom through the central part of the saidshaftand over the sheave without necessarily touching in any way theinterior of the said shaft, and in this way the shaft is not at allcovered by wax.

The spindle is kept suiciently hot to, by conduction, keep the space inthe shaft e warm and the wax on the thread in good working temper.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. The combination with the horn, its spindle, and the hollow shaftextended through said spindle, of a thread-conducting tensionsheaveabove said shaft and having its periphery arranged within the line ofopening` IOO of said shaft, and the stationary wax-pot arrangedimmediately below the open end of and in direct line with the saidhollow shaft, substantially as described.

2. A rotatable horn provided with a hollow central shaft for athreadpassage, means to maintain said hollow shaft hot throughout itslength, a whirl, a sheave peripherally alined with the axis of saidshaft, and located above the same, a stationary wax-pot locatedi1nmediately below and in line witlrsaid hollow shaft, and a wi per, allcombined substantially as described, whereby the thread may be led fromthe wax in the said wax-pot, wiped and then led centrally through saidshaft over said sheave to the whirl,substantially as described.

3. A rotatable horn, a spindle supporting` the same, -a hollow shaftwithin said spindle and rotating therewith, said shaft bein g separatedfroln said spindle in its upper portion to constitute a closedheat-chamber, a hotwater jacket surrounding the lower part of thespindle and shaft, a wax-pot below the shaft, a sheave mounted on thehorn above the said hollow shaft, said sheaye having its periphery inthe axial line of said hollow shaft1 and a whirl, all combinedsubstantially as described, whereby the thread may be passed through thewax in said waxpot and therefrom through the hollow horn-shaft to saidsheave and whirl, substantially as described. In testimony whereof Ihave signed my naine to this specification in the presence of twosubscribing; witnesses.
